Impact of eBay on the spread of invasive species

Today I was reading the news and came across this article about how eBay is aiding the spread of invasive species. Below is the link to the article. In the article, they talk about how over a 50 day period researchers were able to monitor from the supply side (they didn’t have access to private information like geographic location information to confirm regions actually doing business) of the sale of invasive species, in which countries they were being offered from and how often they were available. One of the invasive species they found was up for sale most often was the passion fruit, which is highly invasive in the tropics.

This article particularly interests me because in my conservation biology class we have been looking at the impacts of invasive species on biodiversity and ecosystems. We did a lab where we went to Jacobsburg Park and went to an edge (where the park meets the parking lot). We identified the invasive species, saw first-hand the impacts the invasive species were having on native species (ie crowding out and the suffocation of native species). We then went out in the field and had the opportunity to remove purple loosestrife. I also have come in contact with invasive species in this class- seeing the Japanese Knotweed on the Delaware River and the purple loosestrife when we went with Professor Brandes to Sullivan Park. In reality ever outing I go out on whether in this class or any of my other courses invasive species are present.

The last section of the paper starts with quote from the study’s author, Franziska Humair, “To put it briefly, the vast majority of invasive species can be easily obtained with just a click of the mouse.” A frightening idea, given how harmful invasive species are and how now they are being spread by everyday people over the internet without any monitoring.

Birding

Today for conservation biology lab we took a trip to Mariton Wildlife Sanctuary. Mariton is a 200 acre park that is located over the Delaware River. The purpose of our lab was to compare the species richness and the diversity of the birds in two locations, one in the center of the park and the other along the edge of the sanctuary. To do this we went to our assigned spots in the park and in 15 minute intervals we observed and recorded the birds we heard and saw. Fortunately the Preserve Manager, who is really good at identifying bird calls and bird type,s came along with us to help us identify each bird call and sighting. While we were doing this and I was listening for bird calls and trying to identify each bird I kept thinking of this quote from The Diary of a Citizen Scientist where Russell writes, “When you’re a hammer everything looks like a nail, and when you’re looking for the larval burrow whole of a Western red-bellied tiger beetle, you see a surprising number of holes you’ve never seen before. Usually not the same size or shape, but you look inside anyway because you want to know: who lives in all these holes? (117).”

When we first started to listen for birds, I heard sounds I usually do not notice and every sound I heard I thought was a bird, when in reality the Preserve Manager said some of the sounds I was hearing were insects or frogs in the park. I really identified with Russel’s comparison to when you are a hammer everything looks like a nail and while I was listening for bird sounds for the first time everything sounded like a bird call. When the park manager would tell me they were not bird calls I was so curious what animal it was, but unfortunately he didn’t know for sure.

Some of the birds we identified at Mariton were common birds like cardinals and blue jays, but we also identified some other types of birds. Below are their names and pictures:

Red belly woodpecker:

Tuft Titmouse:

Downy Woodpecker:

Turkey Vulture:

 

Bushkill Park Update

On Friday Jeremy, Lori and I went to our site, Bushkill Park, and met up with Professor Brandis. The first time we had ever gone to our site we were pretty intimidated because there were signs all over the place that said “private property” and signs stating the the fine for trespassing on the property. Unfortunately on our last trip we didn’t get to explore as much as we had hoped we would. So compared to our last trip this trip was much more successful. When we arrived at the site Professor Brandis was already there and met the groundskeeper of the park- he is actually a man who used to work in dining services at Lafayette, but is now retired. He was able to give us a little information about the history of the park and told us that it was fine if we walked along the river on the side of the park. He was also able to give us the name of a guy who has lived near the park for a very long time, and he said he thinks the guy would be very interested in talking to us about our site. We are really excited to reach out to him and hear his story!

Our site is really interesting because it used to be an amusement park that was closed down due to damage from a huge flood in 2004 (from Hurricane Ivan. It was a 100-year flood). Our site is surrounded by the Bushkill River, and even though we weren’t able to enter the park grounds we were able to walk along the river and see a lot of our site. We learned while we were there that at one point was a dam on the river and also an old mill that used to be right on the river! We are really interested in both of these and looking forward to finding out more about them. We also can across an open field (meadow like) and we are really interested in looking into what it was used for. We are hoping to try and take a trip to the Easton Public Library to look at some archives to see if we can find any new information.

We came across some wildlife at the park- we saw deer tracks, we saw a bunch of ducks on the river, we saw a groundhog and we also saw a red fox. Professor Brandis was climbing up one of the banks of the river and the red fox was right at the top of the bank, by the time I had gotten up the bank the red fox was on the move, running across the field and I only saw it for a quick second as it ran underneath a building.

Screen Shot 2015-09-27 at 8.15.51 PMWe came across this building on the back of the property. It was really interesting because on the side of it is a painting of a mill- we are wondering if it has anything to do with the mill that used to be on the river! On the other side of the building is a door frame and if you look you can see grass that is growing inside the building.

If you look closely you can see some people sitting on the rocks.Screen Shot 2015-09-27 at 8.16.50 PM This is a picture Lori took with her back toward the river looking at the side of the park.Screen Shot 2015-09-27 at 8.17.28 PMScreen Shot 2015-09-27 at 8.17.43 PM These are some views looking down the river.

SOS

This weekend I went to Syracuse University for Family Weekend to visit my sister who is a freshman there. My sister lives in a dorm that is located on a hill above the academic buildings and the library. To allow students an easier route then following the road all the way down to the main part of campus, they have this really long enclosed staircase that students can use to get down to the other buildings. It is really interesting because as you walk down the stairs there is art all over the inside on the walls (and by art I mean street art). As I was going down the stairs I noticed this piece that really stood out to me. Of course I like the idea of the nature and city scene built into the ‘SOS,’ but my favorite part of the piece is that in between the panels you can see the trees and real ‘nature’ in the background. I would love to be able to see this picture in 20 years from now and see what ‘nature’ looks like in the background.

Quotes from this week:

“When I paused to lean on my hoe, these sounds and sights I heard and saw any where in the row, a part of the inexhaustible entertainment which the country offers” (Walden, 173).

“Wilderness gets us in trouble only if we imagine that this experience of wonder and otherness is limited to remote corners of the planet, or that is somehow depends on pristine landscapes we ourselves do not inhabit. Nothing could be more misleading” (Cronin, 88).

Leaf Rubbings

I volunteer with a girl scout troop in Easton and today was our first time of the semester to go down and see the troop. When I got down the Boys and Girls club I was pleasantly surprised that our craft was centered around celebrating the beginning of fall. To celebrate we went on a nature walk with the kids and collected the leaves that have already fallen off the trees. It was nice to take the time out of the day to walk outside and it was a fun experience to be outside with elementary school aged kids and hear their perspectives and thoughts about nature. When we finished our walk we took the leaves and used crayons to make leaf rubbings. After we used mod podge and glued some of the leaves we found on to our pictures. Below are some of the pictures the girls in the troop made. It was a nice little encounter with nature.

They Paved Paradise

Lyrics:

They paved paradise
And put up a parking lot
With a pink hotel, a boutique
And a swinging hot SPOT
Don’t it always seem to go
That you don’t know what you’ve got
‘Til it’s gone
They paved paradise
And put up a parking lot

They took all the trees
And put them in a tree museum
Then they charged the people
A dollar and a half just to see ’em
Don’t it always seem to go,
That you don’t know what you’ve got
‘Til it’s gone
They paved paradise
And put up a parking lot

Hey farmer, farmer
Put away that DDT now
Give me spots on my apples
But LEAVE me the birds and the bees
Please!
Don’t it always seem to go
That you don’t know what you’ve got
‘Til its gone
They paved paradise
And put up a parking lot

Late last night
I heard the screen door slam
And a big yellow taxi
Come and took away my old man
Don’t it always seem to go
That you don’t know what you’ve got
‘Til it’s gone
They paved paradise
And put up a parking lot

I said
Don’t it always seem to go
That you don’t know what you’ve got
‘Til it’s gone
They paved paradise
And put up a parking lot

They paved paradise
And put up a parking lot
They paved paradise
And put up a parking lot”

 

I chose to post this song because the message of it really hits home and highlights the issues of industrialization and the the idea that society is responsible for destroying the environment. One line that really sticks out to me is ” Don’t it always seem to go that you don’t you know what you’ve got ’til it’s gone”-that’s usually how it seems when it comes to environmental issues. We build and we build and it seems so great, and then once we sit back and look at what we’ve done it is put in perspective.

Sights Worth Seeing

Yesterday morning when I woke up at 7:30, my morning routine was pretty standard- got up, washed my face, got changed, made breakfast, packed my bag. As it approached 8:20, my cell phone went on the kitchen table, where it would be staying for the majority of the day. When I traveled to New Zealand over interim, I essentially had no phone or internet access for 3 weeks, so the thought of not having my phone wasn’t too terrifying- but that was me being halfway across the world, on a completely different time zone (who was I going to talk to?)  and still having access to my cell phone for photos. When I told my parents our class was going on a kayaking trip their response was “have fun, send lots of picture.” So going into the trip the not having a phone for pictures was a little unsettling.

Once we got on the river, ie Lori and I in a tandem kayak- a kayak that seemed to really favor any direction but straight (disclaimer it may have or may not have been the paddlers who were the cause of this), I noticed we kept mentioning to each other that we wished we could have taken photos. However, as we continued to paddle down the Delaware River we saw some magnificent sights. One of my favorites was the fawn that was running up and down the bank of the river. It just so happened that as our kayak directing us to right, we were able to see through the brush a baby fawn prancing through the brush. Another sight I personally enjoyed was the heron that was perched on a rock that was partially submerged in the river. My family has recently moved to Sanibel Island in Florida,a place where the wildlife is outstanding and something the island is really proud of. When we are down there, my parents are always bird watching, and one of their favorite birds to look out for is the Blue Heron. In our house we have many pictures, sculptures etc of herons. So that sight was particularly exciting to me. However, my absolute favorite moment of the trip was when we saw the ducklings, who had yet to molt, trying to fly. Lori and I actually stopped paddling so we could watch the ducklings as they propelled themselves down the river in attempt to get themselves up in the air. It was one of the cutest things I’ve ever seen.

When I woke up yesterday morning I was uneasy about not being able to take photos on the trip, however I am grateful that I didn’t have the opportunity. I’ve seen this when my family goes on vacation, sometimes taking photos causes us to miss the full experience. We get so wrapped up in trying to get the perfect picture that our experiences aren’t the same. I also see it even more when I go to do something with my friends, sometimes it feels like the only reason they want to go is “for the Instagram,” and not for the experience. They spend the whole time we are there trying to get the perfect shot and find the perfect filter that by the time they are done they haven’t even gotten to experience the event (but don’t worry, they usually end up getting a satisfactory number of likes on their photo that it makes the “experience” worth it).  If we were to have had our phones on this trip I definitely would have missed out on a lot of the wildlife I saw on the river. I also wouldn’t have been in touch as much with all my senses. One moment that really stands out to me was right when we were about to unload the kayaks from the river and we were able to hear the bird callings. The sound was so magnificent, radiant and consumed the air. Although the other group of people who were floating down the river were disruptive to us and our group discussion, it was in a way nice to have them as a way to compare our experiences and to help me appreciate what we had just experienced. I can guarantee the other group of people missed opportunities and experiences (like the bird calls) that I was able to have.

Humans’ Effect on Earth

I came across this article over the summer and I think that is it filled with some really impactful and powerful images of humans’ impact on earth. I would venture to say that these are some of the best quality pictures I have seen to depict the impacts of over development and overpopulation on our planet.

http://www.washingtonpost.com/national/health-science/humans-staggering-effect-on-earth/2015/05/13/01c9b7e2-f974-11e4-9030-b4732caefe81_gallery.html?postshare=9591432712880146

To me one of the most powerful images in this set for me is the photo of the bird that died from ingesting plastics. While at first glance it is a very disturbing picture, I think it has a very powerful meaning and really highlights the impact that every human can have on combating environmental issues. A lot of times with environmental issues it can seem like it is hard for an individual to make a difference, but this imagine reminds you that the individual can make a difference, and in this case with the proper disposal of plastics could have saved a life.

On Monday when we were out looking around campus at various places and went to the back of Watson Hall, we saw the fence with the sharp edges, we heard and saw route 22 and we saw the green pipe right in the middle of “nature”. While we were out there my mind immediately flashed back to this article, specifically the photo of the coal burning power plant in the United Kingdom.
